Ruthenium-Catalyzed Propargylic Reduction of Propargylic Alcohols with Hantzsch Ester

Ruthenium-catalyzed propargylic reduction of propargylic alcohols bearing a terminal alkyne moiety is accomplished by using Hantzsch ester as a nucleophilic hydride source. A variety of secondary and tertiary propargylic alcohols are reduced to the corresponding propargylic reduced products such as 1-alkynes in excellent yields. Some mechanistic studies indicate that ruthenium-allenylidene complexes may work as key reactive intermediates.

Biarylphosphonite gold(I) complexes as superior catalysts for oxidative cyclization of propynyl arenes into indan-2-ones

Striking gold: A series of variously functionalized propynyl arenes was smoothly converted into indan-2-ones by a new gold(I)-catalyzed oxidative cyclization process. [LAu]NTf2 (Tf=trifluoromethanesulfonyl) is a superior catalyst both in terms of yield and kinetics for the present transformation. Copyright

Chiral Carbenoids: Their Formation and Reactions

Carbenoids, generated by metalation or halogen-metal exchange reactions, have been prepared from chiral vinyl and cyclopropyl halides.The reactivity and stereochemistry observed in the reaction of these carbenoids has been interpreted as being due to meta
